FIELD OF THE INVENTION

The present invention relates generally to a device that can be attachedto the shaft & hosel of a golf club to dampen vibrations. Morespecifically, the device comprises of a unique, reversible securingmechanism to prevent shifting of the device when the golf club is inuse.

DESCRIPTION OF THE PRIOR ART

Prior art which relate to the present invention, includes the followingpatents:

Artus, U.S. Pat. No. 5,277,423 discloses a striking head having a hoselwith an extended shaft fixed to the hosel. A vibration dampening meansis fixed on the shaft. The vibration dampening means comprises aviscoelastic later and a rigid tubular sleeve. The rigid tubular sleeveconstrains the viscoelastic layer to the shaft. The vibration isadditionally integrated into an altered shaft. The present inventionintroduces a vibration dampener device that is placed over the hosel andshaft of any golf club. Unlike the prior art presented, the presentinvention has the ability to be removed from a user' club and does notstructurally alter a golf club shaft. The present invention allows thegolf club to maintain its structural stability.

Ling, U.S. Pat. No. 5,759,113 discloses a golf club that comprises astriking head having a hosel. A shaft is fixed to the hosel of thestriking head and a grip. Attached to the shaft are constrained layerdampers. The layer dampers are non-tubular and each layer is constrainedindependently. Unlike the prior art, the present invention is tubulardevice that does will not hinder the aerodynamic flow of the shaft whilea user is swinging the club. Unlike the non-tubular layer dampers, thetubular design of the present invention ensures and vibrations of shockare passed through the dampening component of the present invention.

Todd, U.S. Pat. No. 6,544,129 discloses a vibration dampening device foruse on the shaft of a golf club. The device comprises of a dampeningunit including a strip of elastomeric material that encircles theexternal periphery of a golf club shaft. The strip of elastomericmaterial comprises a viscoelastic polymer. A clip unit is used toreceive both the dampening unit and the periphery of the shaft of a golfclub. Unlike the prior art, the present invention utilizes an outerjacket with a reversible fastening system (e.g., latches, hooks, snaps,buttons, straps, hook-and-loops strips, magnets, ties, etc.) to securethe inner dampening component to a golf club.

In reference to U.S. Pat. Nos. 6,155,932; 6,231,456; and 5,294,119, theprior art includes several different vibration dampening devices forgolf clubs. While the prior art disclose devices for dampening vibrationin a golf club, the prior art fails to isolate vibrations that are closeto its source. The present invention is designed to fit over the hoseland shaft of the golf club to immediately dampen the vibrations causedby the striking head. Furthermore, the inner dampening component of thepresent invention is provided with a release through a block window onthe outer jacket. Many of the prior art introduced disclose a vibrationdampener that completely constrains the damper component onto the shaft.Viscoelastic materials exhibit both behaviors of viscous materials andelastic materials. However, when a load is placed and released from thematerial, mechanical energy can still be released from the viscoelasticmaterials. By binding the viscoelastic materials tightly or embeddingthe materials directly into the golf clubs, the ability of the materialto absorb energy is altered. As a result, the remaining mechanicalenergy that is not dampened is directed back into the golf club. Thepresent invention introduces an outer jacket window allowing the partialmechanical energy to be released as slight temporary deformations to theinner dampening component.

BACKGROUND OF THE INVENTION

Vibration from golf clubs after impact with a ball is one of the knowncauses that induce injury to a player. When a user hits a golf ball,vibrations travel from the head of the club, up the shaft, and into theplayer's arms holding the club. Continuous exposure to vibrations from agolf club can place a large amount of stress on the muscles and jointsof a user's arms. Several vibration dampening devices have beendeveloped to combat the vibration resulting from the impact of golfballs. However, many of the existing dampening devices are simpleviscoelastic cuffs that are attached in an arbitrary position on theshaft of a golf club. The present invention introduces a new vibrationdampening device that is uniquely designed to attach to the base of theshaft and the hosel of the club head. The design of the presentinvention allows it to lock onto the shaft & hosel of the golf club andimmediately dampen vibrations caused by the head after impact with agolf ball. The vibrations originating from the club head can also causethe user to tense up during a swing. This can also disrupt proper swingform of the user and lead to other injuries. The reduction orelimination of these vibrations allows the present invention to allowusers to perform proper golf swings consistently and with less vibrationduring impact.

DETAIL DESCRIPTIONS OF THE INVENTION

All illustrations of the drawings are for the purpose of describingselected versions of the present invention and are not intended to limitthe scope of the present invention.

In reference to FIG. 1-7, the present invention is a vibration dampeningdevice that comprises of an outer jacket 1 and an inner dampeningcomponent 2. The outer jacket 1 is the component of the presentinvention that is able to secure the inner dampening component 2 ontothe shaft of the golf club. The inner dampening component 2 is thecomponent of the present invention that wraps around the shaft and hoselof the golf club to absorb any vibration that originates from the headof the club. The present invention is encompassed about the hosel andthe shaft to immediately dampen the resonating vibrations from the headwhen a user strikes a golf ball. The inner dampening component 2 of thepresent invention can be made of the materials including neoprene,buna-N, silicone, EPDM, natural gum, viton, styrene butadiene, vinyl,santoprene, epichlorohydrin, butyl, chlorosulfonated polyethelene, anon-dilatant newtonian material, or any other suitable materials withexceptional visco-elastic properties. In the preferred embodiment of thepresent invention, the inner dampening component 2 is made with amaterial with high visco-elastic properties. The inner dampeningcomponent 2 is able to dampen vibrations due to its visco-elasticproperties. Visco-elastic materials are characterized to have both theproperties of an elastic material and the properties of a viscousmaterial. Elastic materials are able to store energy received from aload and later release that energy when the load is removed. Unlikeelastic materials, viscous materials do not store energy and energy islost. Visco-elastic materials have the ability to absorb a large portionmechanical energy and transform it into thermal energy. As a result,mechanical energy from shock or vibration is dramatically reduced,preventing it from travelling up the shaft of a club into the user'shands.

In reference to FIG. 8 and FIG. 13, the inner dampening component 2 istube shaped and comprises a slit 23, outer ribbings 24, a external masselement 25, a shaft channel 21, and a hosel channel 22. The slit 23 is acut opening positioned on the side of the inner dampening component 2arranged in parallel relationships along the length of the innerdampening component 2. The slit 23 allows the user to slip the innerdampening component 2 over the shaft and hosel of the golf club. Theouter ribbings 24 are ring protrusions positioned on the outer surfaceof the inner dampening component 2. The outer ribbings 24 are patternedalong the entire length of the inner dampening component 2. The externalmass element 25 is a protrusion positioned on the outer surface of theinner dampening component 2 opposite of the slit 23. The shaft channel21 and the hosel channel 22 are both cylindrical holes that traversethrough the center of the inner dampening component 2. The shaft channel21 is sized to tightly fit the shaft of the golf club. The hosel channel22 is sized to tightly fit the hosel portion of the golf club. Thepresent invention is designed to fit on the base of the shaft close tothe club head. On the lower portion of a golf club, the shaft has aradius smaller than that of the hosel. Naturally, the hosel channel 22will have a larger radius than the shaft channel 21. In the preferredembodiment of the present invention, the shaft channel 21 occupies sixtypercent of the length of the inner dampening component 2 while the hoselchannel 22 occupies the remaining forty percent. However, in otherembodiments of the present invention, the length ratio of the shaftchannel 21 and the hosel channel 22 can be adjusted to produce differentresults. More specifically, in other embodiments of the presentinvention, the hosel channel 22 may be absent leaving only the shaftchannel 21. This allows the user to attach the present inventiondirectly to the shaft only. The shaft channel 21 comprises a shaft gripribbing 211 and the hosel channel 22 comprises a hosel grip ribbing 221.In the preferred embodiment of the present invention, the hosel gripribbing 221 are thin fine rings patterned and positioned concentricallyon the inside surface of the hosel channel 22. With the shaft channel 21being longer than the hosel channel 22, the shaft grip ribbings 211 arewider ribs patterned and positioned on the inside surface of the shaftchannel 21. The ability to tune the shaft ribbing to match the optimalfrequencies of a specific golf club is known as modulated ribbing. Inthis embodiment, there are two discrete frequency bands within theribbing. Other embodiments contain one or more spatial frequencies ofribbing depending on whether the part is to be tuned for a specific typeof club (e.g., irons or drivers), or made to be a versatile broadbanddampening element. In reference to FIG. 6-7, the slit 23 on the innerdampening component 2 comprises of corresponding ledges 231. Thecorresponding ledges 231 on the two sides of the slit 23 ensure that theinner dampening component 2 fully encompasses the shaft and hosel of thegolf club.

In reference to FIG. 11-12, the outer jacket 1 is a tubular casing thatis formed by two semi-tubular parts including a top portion 11 and abottom portion 12. The outer jacket 1 is a rigid component that securelyfastens the inner dampening component 2 to the golf club. The topportion 11 and the bottom portion 12 are separate pieces that unitetogether to form a cylindrically shaped shell for the present invention.The top portion 11 being semi-cylindrically shaped comprises a blockwindow 112, top jacket ribbings 111, and a plurality of latch loops 113.The bottom portion 12 similarly being semi-cylindrically shapedcomprises bottom jacket ribbings 121 and a plurality of latches 122. Theblock window 112 is an opening positioned on the top portion 11 shapedto correspond to the shape of the external mass element 25 on the innerdampening component 2. The block window 112 is positioned on the topportion 11 to allow the top portion 11 to be aligned consistently withthe inner dampening portion. The top jacket ribbings 111 are ridgesdisposed along the length of the concave side of the top portion 11. Theplurality of latch loops 113 extends from and is positioned along thelength of the two straight edges of the top portion 11. The bottomjacket ribbings 121 are ridges disposed along the length of the concaveside of the bottom portion 12. The plurality of latches 122 positionedalong the outer surface of the bottom portion 12 adjacent to the twostraight edges. The plurality of latch loops 113 and plurality oflatches 122 are positioned on the top portion 11 and the bottom portion12 to correspond to one another. The top portion 11 and the bottomportion 12 are connected by means of the plurality of latch loops 113engaging the plurality of latches 122 to form the outer jacket 1. Theconnection of the top portion 11 and the bottom portion 12 allow the topjacket ribbings 111 and the bottom jacket ribbings 121 to combine andform a complete ring ridge pattern corresponding to the outer ribbings24 of the inner dampening component 2. In an alternative embodiment, theouter jacket 1 comprises of a top portion 11 and a bottom portion 12connected together by at least one hinge to form a singular piece asopposed to two separate pieces. The at least one hinge permits the topportion 11 and the bottom portion 12 to swing open and close withoutdetachment from each other. A plurality of latch loops 113 and aplurality of latches 122 are positioned at the ends of the top portion11 and the bottom portion 12 opposite to the at least one hinge. The topportion 11 and the bottom portion 12 are connected by means of theplurality of latch loops 113 when the outer jacket 1 is in a closedposition and subsequently allow the bottom jacket ribbings 121 tocombine and form a complete ring edge pattern corresponding to the outerribbings 24 of the inner dampening components 2. The outer jacket 1comprises of an outer element where the outer element is a surfacemodification selected from the group consisting of at least oneaerodynamic groove, a gripping element, or a marketing element.

In other embodiments of the present invention, the top portion 11 andthe bottom portion 12 may have a hinge connection with the plurality oflatch loops 113 and the plurality of latches 122 for securing the innerdampening component 2 to a golf club. The plurality of latch loops 113and the plurality of latches 122 are male and female components of areversible fastening system 13. The reversible fastening system 13comprises a male and a female fastener component which is, but notlimited to, at least one latch and latch loop, hooks, snaps, buttons,straps, hook-and-loop strips, magnets, or ties. In the preferredembodiment as previously described, the reversible fastening system 13comprises of a plurality of latch loops 113 and a plurality of latches122. However, in alternative embodiments, the fastening system is notlimited to latches and loops but may be any fastening components capableof securing the top portion 11 and the bottom portion 12 together toform the outer jacket 1 which in turn, secures the inner dampeningcomponent 2 to the shaft. In yet another embodiment, the reversiblefastening system does not comprises of a male and a female fastenercomponent. Instead, the reversible fastening system 13 may be a rubberband or any component which secures the outer jacket 1 or the innerdampening component 2 to the shaft of the golf club. However, it isimportant to note that the reversible fastening system 13 does notcompromise weight and does not comprise aerodynamics of the overallpresent invention. Furthermore, the reversible fastening system shouldprovide for a certain level of grip and is compatible with the externalmass element 25.

In another embodiment of the present invention, the outer jacket 1 canfurther comprises of external ribbings that are positioned along thelength of the top portion 11 and the bottom portion 12. The externalribbings provide the outer jacket 1 with an aesthetic design and canfurther provide the present invention with a more aerodynamic shape. Asa result of the aerodynamic shape, the user will experiences a smootherswing with minimal air resistance.

In yet another embodiment of the present invention, the outer jacket 1can be made from a cloth material. In this embodiment, the outer jacket1 is bound about the inner dampening component 2 by means of adhesivesor fastening straps such as hook-and-loop fasteners. The outer jacketcan be a single piece or a two piece jacket. The single piece can bemade with the loops distributed on an outer side of the outer jacketwith the hooks being positioned on one end of the inner side of theouter jacket. This allows the outer jacket to loop around the innerdampening component and hook onto the loops on the outer side. The twopiece jacket can be made in a similar fashion where the top portion ismade with the loops distributed on the outer side and the hooksdistributed on the two ends of the inner side of the bottom portion. Inother embodiments of the present invention, the outer jacket can useother means of adhesives to be fastened onto a golf club shaft.

In reference to FIG. 8-10 and FIG. 13, to assemble the present inventiononto a golf club, the inner dampening component 2 is first wrappedaround the shaft and hosel of the golf club. The top portion 11 of theouter jacket 1 is then aligned and engaged to the inner dampeningcomponent 2. The engagement of the top portion 11 to the inner dampeningcomponent 2 allows the external mass element 25 to be inserted andfitted into the block opening. Once the top portion 11 has engaged theinner dampening component 2, the bottom portion 12 is engaged to the topportion 11 by means of the plurality of latch loops 113 and theplurality of latches 122. The connection of the outer jacket 1 over theinner dampening component 2 tightens and secures the inner dampeningcomponent 2 to the golf club. The hosel grip ribbing 221 and the shaftgrip ribbing 211 provide additional surface area contact between theinner dampening component 2 and the shaft of a club. The increasedsurface area contact allows the increased amount of surface area inwhich mechanical energy can be absorbed into the inner dampeningcomponent 2. Furthermore, the increased surface area of contact betweenthe inner dampening component 2 and the shaft increases the grip toprevent the shifting of the overall device. To prevent the shifting ofthe outer jacket 1 over the inner dampening component 2, the outerribbings 24 of the inner dampening component 2 corresponds and fits tothe top jacket ribbings 111 and the bottom jacket ribbings 121. Theexternal mass element 25 protruding from the block window 112 alsoprovides additional stability of the outer jacket 1. With the presentinvention secured over the base of the shaft, vibrations at the clubhead caused by impact are immediately absorbed by the inner dampeningcomponent 2. The unique positioning of the present invention at the baseof the shaft also contributes to the overall reduction of remainingvibrations that are able to travel up the shaft. By immediatelyabsorbing high frequency vibrations directly after the club head, anyremaining weaker vibrations are required to travel up the entire lengthof the shaft. The distance of travel along the length of the shaft tohandle serves to further weaken or eliminate the remaining vibrations.

In one embodiment, the inner dampening element contains an external masselement which protrudes through a block window in the outer jacket. Thisdesign allows for the maximal vibration reduction while offeringnegligible product weight with respect to the total weight of an entiregolf club. As a result, the attachment of the present invention will notaffect the swing of a user. Instead, by absorbing vibrations fromimpact, the users are able to swing with more confidence without fearingthe pain caused by mishit. In another embodiment, the inner dampeningcomponent contains modulated ribbings that focus the vibrational energyinto the protruded mass element.

The present invention is also designed to aerodynamically match with theshaft of a golf club to prevent drag or alterations to user's normalgolf swing. In one embodiment, aerodynamic grooves are added to theouter jacket. In another embodiment, the aerodynamic grooves areoptimized for easy gripping during reversible attachment, since elderlygolfers may lack precise hand coordination. Using the present invention,the user is provided with prolonged endurance during practices. Thisallows the user to further perfect their stroke for an improved golfingexperience.
